vented certain new and usei'ul Improvements 1n Windows, of which thefollowing is a specilication. l

This invention relates to a window or door of the multifold type, beingparticularly concerned withthe mountings for the individual'window ordoor sections, and the means by which such sections are guided in theirmovements.

It is to be noted that the present improvementv is applicable towindowsv or doors composed ot' two or'more sections arranged to befolded upon each other 'for the purpose of aii'ording a wideV passage.Iny eX- plaining our invention reference will be made throughout thespecification and drawings to a windowV constructiononly,

'although it should be borne in mind that y'substantially no modicationsare required in order thatthe same invention vmay be adapted for usewith folding doors.

The present window construction has for its objects numerous purposes;itrissimple and inexpensive to build and install; it positively guidesand securely holds the window sections against accidental dis-`placement; itpermits 'the window to be opened or closed without`binding' Iof Ythe parts and without undue frictionglit presents a `wideclearance when opened, without proyecting the window sections 1nwardlyor outwardly tofany considerable eX- 'tentg' and itk provides aconstruction which isadaptable to two or more window sections,

as may be required. lThese and othery objects are attained bythe'present invention, as willfmore fullyhereinaiter appear from thespecification and and from the accompanying drawings, 1n which Figure 1is a View inelevaton Showing, in dosedp'ostmn a multiplerwindow consistying of `four saslies; n Y

The window of our invention is shown comprehensively in Fig. 1, and mayconsist of a plurality of sections orsashes, say tour kin number, whichare designated as A, B, C, and D. These sashes are arranged within asuitable frame 14, having a sill 15, side vjambs 16, anda head` 17. Eachof the' window sashes isy constructed substantially alike, with stiles18 and top and 'bottom rails 19 and 2O,A respectively. Hinges 21 ,serveto connect together the window sashes and to permit the folding actionwhich will presently be described.

SashD, hoi'vever, is supported at its upper 'and lower ends by means ofsupports resembling those provided for sash B, but differingl in thisrespect: The lower support consists ofaplate '56 fixedly secured to thelower rail of the window and having an upturned end portion 5T whichmaybe inset and secured in the manner shown (see Fig. 10) rhis platehasno sliding motion whatever, but in other respects is similar to theplate provided for. section "B,'in thatiit carries a ball 40 whichtravels within the same grooved plate 41 as does the ball in the plate36. Likewise the support secured to the upper rail of the sash Dconsists of a plate 58 tixedly secured thereto, and carrying a pin androller and 52 respectively, which lat` ter engages with the same guiderail 54 as does the roller on the slidable plate 47.

As appears best in Figs. 2 and 8, the outer edges of the stiles of eachof the sashes may be provided with a groove 59 or a tongue 60 arrangedto coperate, when alined, for the purpose of making a tight jointbetween the sashes. Likewise spring moldings 61 may be arranged upon theamb of the frame to be engaged by the sashes D and A when the window isclosed. Upon the sill and head of the frame stops 62 may also bearranged so as to conine the swinging movements of the window sashes t0an outward direction, or, if preferred, may be so arranged as to confinesuch movements to an inward direction. By such means as these, thespaces around the window edges are covered andprotected against theentrance of rain, wind, etc.

n Figs. 11 and 12, we have shown two possible positions for the windowsashes. ln these positions, the window is not entirely but onlypartially open. As appears in Fig. 11, the sashes A and B remain innormally closed position, while the sashes C and D are swung `outwardlyto open up substantially one-half of the window sash. ln Fig. 12, thesashes A and B alone have been outwardly swung, while the sashes C and Dhave been made to slide into the position shown. The amount of clearanceadorded by the window, when in either of the positions shown in Figs. 11and 12, is substantially the same. In order to fully realize theadvantages of your invention, the sashes at the window extremitiesshouldbe slightly wider than the intermediate sashes. The dierence inwidth would be represented approximately by the thickness of the windowsash, plus the clearance space between two sashes when folded intoparallel relation. For instance, if the sash is l in thickness and theclearance between the sasheswhen folded together amounts to fg, then theoutside sashes should be L15-,15" wider than the remaining sashes. Thereason for this is readily apparent by an inspection of Figs.

fl-l yand 12, where two sashes of unequal l'are shown in 'this ligure.During closing ofthe Window, the sashes are alined, at which time abumper block 64 secured to the sash C engages with the rounded edge G3of the slide plate to force the same back into the guideway.

It will be noted that the present window requires for its construction arelatively few parts, some of which are interchangeable. The window mayreadily be installed by cutting the edges of the rails and stiles toreceive the guide-ways, etc., and arranging upon the window frame theother parts which form the mountings for the window. It should beobserved that the window sashes need not be mortised for the receptionof any of these parts. T he number of window sashes to which ourinvention is applicable may vary from two up, it being necessary merelyto duplicate the mountings for each pair of sashes added.

In operation it will be found that the sashes of the present window maybe moved easily without any binding. This is because of the manner inwhich the sashes are secured to the window frame and to each other. Atleast one half of the sashes are independently supported and areprovided with anti-friction members to permit of an easy sliding action.For these reasons the opening and closing operations may be readilyeiiected. The present window construction is especially advantageous inthat the sashes are connected directly to each other without theintervention of mullions which obstruct light and air. Our window, whenfully opened, affords a clearance substantially equal to the entirewidth of the frame, the only obstruction remaining being that caused bythe aggregate thicknesses of they several sashes.

We claim:

1. A multifolding window comprising: a frame; a plurality of sashes, notless than four, pivotally connected together; and connections betweencertain of the sashes and opposite sides of the frame*those with one endsash being pivotal only, those with the other end sash being pivotal andsliding, and those intermediate being pivotal and slidingy andeXtensible, all of the connections with the frame being situated in asingle plane lying substantially midway between the inner and outerfaces of the sashes when in closed position, substantially as described.
